APPARATUS FOR MAKING ARTIFICIAL FUEL.

Application led April 2, 1921. Serial No. 458,138.

This invention relates to apparatus for the lmanufacture of artificial fuel and has for its object the provision of an apparatus for converting waste material such as lignite or other non-colring coal and waste wood of all kinds into an artificial coal of any desired grade which will have all the advantages with practically none ofthe ldisady vantages of natural coal.

In a separate -application Serial No. 152,-

294, filed March 14, 1921, I have setv forth my process which might be carried out with a different apparatus but the present invention contemplatesthe provision of a specific apparatus for carrying out the process mentioned inthe companion application. The process referred to involves the carbonizing of lignite or other non-coking coal and of wood by distilling separately in suitable retorts to drive ofll the tars and other volatile matter. and also the moisture. The carbonized materials are then pulverized and mixed together and lthen have added thereto a certain amount of the tar previously removed by the distillation referred to, after which the mass is mixed and deposited ontov a hard bed upon which the mass is rolled by means of a speciesl of steam roller having heated rollers whereby the mass will be greatly compressed so as to make a compact homogeneous mass. n

An important and more specific object of the present invention is the provision of a comparatively simple apparatus for very efficiently carrying out the above described process in an expeditious manner,

With he above and other objects and advantages in View, the invention consists in the details of construction, to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings; in

which:-

Figure 1 is a diagrammatic side elevation of my complete device.

Figure 2.is a longitudinal sectional view through a portion thereof.

Figure 3 `is a longitudinal sectional view through the remainder thereof, and the rcmaining figures are detail views of the rolling bed.

Referring more particularly to the draw-v ings the numeral 1() designates a grinderof conventional pattern, which is provided for the purpose of reducing the coal, wood or other carbonaceous material to any suitable size desired. This grinder discharges into the lower end of an elevator. 11 which includes Aan upwardly moving conveyor 12 driven :by any suitable means, not showin At its upper end this elevator 11 discharges into a bin 13 below the lower end of which is disposed a receiving hopper 14 which leads at its bottom into an upwardly inclined casing 15 withinV which is located a screw conveyor ldriven by a beveled gear 17 with which meshes a bevel Oear 18 on a shaft 19 driven by any suitable means.

The upper end of the casing 15 discharges intothe upper end of a retort structure designated broadly by the numeral 20. This retort device comprises an. outer casing 21 provided near its top with a smoke pipe 22 leading to any suitable stack, not shown, `and communicating at its lower end with a suitable lire-box 23 beneath which is a conventional ash y pit 24C. The retort proper comprisesva casing 25 which has its upper end reduced and leading into the upper end of the casing 15 and which has its lower end extending through 'the bottom part of the outer portion 21 of the retortv and terminating in a downwardly inclined chute 26,. A suitable sliding door 27 is provided for controlling the outlet at the lower end of the discharge chute 26. Leading from the upper portion of the inner casing 25 is a take-olf pipe 28 which leads into ay hydraulicv main 29 which conducts the disthe invention or the scope of the subjo-ined claim.

Having described the invention What is claimed isz- An apparatus for making artificial fuel comprising a destruct-ive distillation retort, means for applying steam to the heated solid matter being,- discharged from the retort, a heated hard bed to receive the steamtreated solid matter, a rolling device having 10 heated rolls and operating` upon such heated bed, all arranged in combination substantially as described.

In testimony whereof I aix my signature.

HENRY C. DIERS.
